I have been on mirc karaoke realm for about 2 years now but recently did not utilise this site for more than 6 weeks. When I went to register my nic an email to varify was sent to my email..trouble is my email address has changed as that internet provider is no longer in business and I dont know how to get onto irc to change this address as it is part of the registration requirement.

You should ask the people on the network you're referring to.

mIRC is a *client* for the IRC protocol. mIRC does not administer any networks or servers, that is done by people and organizations hosting IRC servers. Since nobody here administers the network you're referring to, there's not much we can do for you. The people who actually run the servers should know what to do though, so you should connect to the server and ask them (or email them).
